The January 2020 issue of Square Enix’s Monthly Big Gangan magazine revealed last Wednesday that Norimitsu Kaihō (School-Live!), Makoto Fukami (Magical Girl Spec-Ops Asuka), and Etorouji Shiono (Übel Blatt) will launch a new manga titled Deep Insanity in the magazine’s next issue on January 24.
Kaihō and Fukami are credited for the manga’s original work, and Shiono is drawing the manga.
In 2011, a side story manga called Übel Blatt Gaiden ran in Young Gangan Big, the spinoff of the Young Gangan.
Square Enix’s Young Gangan magazine began serializing Shiono’s Übel Blatt manga in 2004.
